No Dice? Roll Them in Your Browser (D&D, Board Games, and More)
2026-06-12
Short answer: you don't need physical dice — roll them on screen. ToolKoala's Dice Roller rolls one or many dice from d4 to d20, shows each result and the total, and every face is genuinely equally likely. No app, no sign-up, runs in your browser.
The classic problem: the dice are gone
Board game night, and the d6 is under the couch. Or you're starting D&D and don't own a d20. Or you just need "a random 1 to 6" and there's no die in reach. A browser dice roller fixes all three — and a digital die can't get chipped, loaded, or roll off the table.
How to use it
- Open Dice Roller.
- Pick how many dice and how many sides — d4, d6, d8, d10, d12, or d20.
- Hit Roll. The dice tumble and settle.
- Read each die; for multiple dice it shows the total automatically.
Each die uses crypto.getRandomValues, so every face has an exactly equal chance — fairer than a real die, which always has slight physical bias.
Handy for
- Tabletop RPGs — roll a d20 for checks, or
3d6for stats, without a dice bag. - Board games — replace lost dice instantly.
- A quick 1-to-N — a single die is the fastest way to get a small random number.
- Settling something — high roll wins.
When another tool is better
- Need a number in a custom range (like 1–500, or no-repeats)? Use the random number generator.
- Picking a name or option, not a number? Try the decision maker or spin the wheel.
FAQ
Are online dice rolls actually fair?
Yes. Each roll uses crypto.getRandomValues, so every face is equally likely — with none of the chips, weighting, or bias a physical die can pick up.
What dice can I roll? d4, d6, d8, d10, d12 and d20 — and you can roll up to 12 at once, with the total added up for you.
Can I use it for D&D and tabletop games? Yes — pick the die type and how many, roll, and read the total. It covers standard RPG and board-game dice.
Does it save my rolls? No. Everything runs in your browser; nothing is uploaded or stored.
